GE12–Mechanically connected tachogenerator with alternating voltage output signal : NORIS Group GmbH

GC_Tachogeneratoren_GE120-121-122_1024x768px

High-quality tachogenerator with alternating voltage output
Suitable for extremely harsh operating conditions
Direct and indirect drive possible
Degree of protection: IP66 (3,000 rpm and above: IP54)
Variable mechanical connections for speed acquisition

Tachogenerators of type GE12 are mechanically connected 1-channel speed encoders with a sinusoidal alternating voltage output signal. They are attached to the shaft via a flange or bracket. The mechanical connection is realised via a coupling. They do not require any power supply. These tachogenerators are suitable for acquiring shaft speeds. Their compact and robust design, as well as their approval by shipbuilding industry classification societies, make them ideal for marine applications.
